CONTAINER FOR VOLATILE LIQUIDS.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed August 6, 1920. Serial No. 401,694.

To all whom c'tmay concern:

Be it known that I, MILTON C. WHITAKER, a citizen of the United States, residing at Baltimore, State of Maryland, have invented a certain new and useful Improvement in Containers for Volatile Liquids, of which the following is a specification.

My invention relates particularly to a container adapted to be used for discharging when desired, small quantities of volatile. liquids, but which is especially adapted to be used as a container for priming fluids used for starting internal combustion engines.

The object of my invention is to provide a container of the above character which is so constructed as to be entirely vapor tight when prepared. for sale and which may be readily opened for the discharge of the liquid, and again closed in a convenient man ner, so as to make it substantially vapor tight. A further object of my invention is to provide a container of this kind having a puncturable diaphragm, which, when punctured may be closed in such a way as to prevent the escape of the vapors of the volatile fluid. In previous constructions the puncturable diaphragms have been provided with circular ridges surrounding the areas to be punctured and disk valves have been brought into contact with the ridge to prevent the outward flow of the liquid when closed. Inasmuch, however, as in such a diaphragm the area to be punctured is comparatively large, and the surrounding ridge is of considerable length, there is a comparatively long distance to be closed by the valve and a correspondingly great opportunity for the escape ofthe contents. For this reason a volatile and comparatively expensive liquid could not be used in such containers. Furthermore, in the previous constructions it was customary to locate the closing valve at one part of the closure in the opening giving access for puncturing the diaphragm and a discharge spout at another portion of the closure. By means of my invention, on the the same opening in the closure which gives access to the diaphragm for the puncture contains both the discharge spout and the aperture-closing means.

Further objects of my invention will ap pear from the detailed description thereof contained hereinafter.

While my invention is capable of embodi-' ment in many different forms, for the purpose of illustration I have shown only one form of the same in the accompanying drawin s, in which;

igure 1 is a side elevation of a. container made in accordance with my invention.

F g. 21s a vertical section of the same, and

F 1g. 3 is a vertical section of a modified form of container made in accordance with my invention.

In the drawings,.referring to Figs. 1 and 2, I have shown a container of oval cross-section made of sheet metal of any desired charactor, as for example, tin, iron, nickel, brass, etc., comprising a main outer wall 1 having a bottom 2 and a top 3 crimped over the edge of said wall. The top 3 has a central opening 4 on the edge of which there is soldered a puncturable diaphragm crimped over a convex member 6 having an inwardly directed cylindrical portion 7 carrying a screw-thread. The screw-threaded portion 7 is provided for receiving a screw-threaded cap 8 having a washer 9 therein to contact with the top of the convex member 6. The

"cap 8 is also interiorly screw-threaded toin the following respects: In this instance, there is a top 14 having an annular groove or recess 15 surrounding an opening 15*, in which there is soldered a convex member 16 having an inwardly projecting cylindrical portion 17 the lower portion of which forms a puncturable diaphragm 1.7, which is screwthreaded to receive a cap 18 having an upper flange 18 overlying a gasket 18", and a spout 19 attached to the lower end of the same, so as to leave a screw-threaded recess 20 to which a cylindrical cover 21 is secured. Said cover 21 has a cork washer 22 fitting over the end of the spout 19, and there is an inwardly directed ridge 23 to retain the washer in place.

In the operation of my invention, referring to Figs. 1 and 2, the container will be filled with any suitable volatile liquid, as for example, a priming fluid which may be ether, acetone, or any other similar material or composition through the opening 4, after which the remaining parts are connected to the container by soldering the diaphragm 5 to the top 3 along the edge of the opening 4. The container is now ready for shipment and sale on the market. \Vhen the contents are to be used, the cap 8, with its attached parts, is unscrewed, and the diaphragm 5 is punctured with a sharp instrument of any kind, after which the cap 8 is again screwed into place and the cylinder 10- is unscrewed, thus disengaging the washer 11 from-the end of the spout 13 and permitting the contents to be discharged, as for example, into the petcocks of an internal combustion engine, by pressing slightly upon the sides of the container. When the desired quantity of liquid has been discharged in this way, the container is again closed by screwing the cylinder 10 into place, thus bringing the small discharge aperture of the spout 13 again into contact with the washer 11 and preventing the escape ofthe volatile vapors of the priming fluid. lVhere the fluid is of a very volatile character and also comparatively expensive, it is necessary to prevent the rapid losses which would occur if the container 'should'permit the escape of vapors of the same therefrom.

The modification of my invention shown in Fig. 3, operates the same as the modification previously described, except that in this instance, the puncturablediaphragm 17 is located on the convex member 16. This construction has the advantageof omitting one of the parts present in the preceding construction, and brings the puncturable diaphragm up to a more accessible position.

Vhile I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing from the spirit thereof.

I claim: I

i 1. A container for volatile liquids having ried in said opening, and a cover closing the end of the nozzle.

4. A container for volatile liquids having a puncturable diaphragm, an opening giving acce'ssto said diaphragm, a nozzle screwthreaded in said opening, and a cover closing the end of the nozzle.

5. A container for volatile liquids having a puncturable diaphragm, an opening giving access to said diaphragm, a nozzle carried in said opening, and a cover closing the end of the nozzle and received in said opening.

A container for volatile liquids having a puncturable diaphragm. an opening giving access to said diaphragm, a nozzle screwthreaded in said opening, and a cover having a Washer closing the end of the nozzle and received in said opening by being screwthreaded to the nozzle portion located in said. opening.

15. A container for volatile liquids having a puncturable diaphragm, a nozzle adapted to discharge the liquid passing through said diaphragm and a closure for the end of the nozzle screw-threaded to the 10' base of the nozzle.

In testimony that I-claim the foregoing, I have hereunto set my hand this 26th day of May, 1920.

MILTON o. WHITAKER.
